A four-septum TEM cell has been proposed as a new radiated radio-frequency immunity/susceptibility test device. The cell provides electromagnetic fields rotating at a very low rate by generating a two sets of balanced-mode fields orthogonally. In this paper, a test method using the cell is clarified, and susceptibility characteristics of two types of microstripline models are investigated to verify the effectiveness of the cell and a role of dielectric material is made clear. In addition, an analysis method of the internal electromagnetic fields, which are different from those used in an ordinary TEM cell, is discussed using a image method.

“…A RF radiated immunity/susceptibility test method using rotating-EM fields is proposed [7], [8]. In this method, since the polarization of the EM fields rotates at a very low rate, e.g., below 1 Hz, the EM fields of whole polarization in a two-dimensional plane can be applied to EUT automatically.…”

A new radiated radio-frequency (RF) immunity/susceptibility test method using an RF-pulsed rotatingelectromagnetic (EM) field is proposed. Controlling the pulse width can generate the RF-pulsed signal having an arbitrary bandwidth. By using such RF-pulsed rotating-EM field as an incident-EM field of the immunity/susceptibility test, it is possible to easily investigate the immunity-weak points of electronic equipments. In this paper, the basic characteristics of the RF-pulsed rotating-EM field are clarified. Moreover, some susceptibility characteristics of a cavity with a slit measured by using the RF-pulsed rotating-EM field are shown as an example.

“…The rotating-EM field can be generated by applying two different DSB-SC signals to two orthogonally arranged antennas [1]. These two DSB-SC signals are given by…”

A new generation technique of the double-side-band suppressed-carrier signals for radiated, radio frequency, immunity/susceptibility test using electromagnetic field of rotating polarization and its basic characteristics are studied. The signal can be easily generated with only one signal generator by using the technique. In this paper, the basic characteristics of the signals generated by using the technique proposed here are clarified, and the uniformity of the field generated in an anechoic chamber by using the signals is evaluated. In addition, a susceptibility test is conducted by using the new system to which the proposed technique is applied. From these results, the effectiveness of our proposed system is confirmed.
